[libvirt] ANNOUNCE: libvirt-glib release 0.1.9
by Daniel P. Berrange 20 Aug '14

20 Aug '14

I am pleased to announce that a new release of the libvirt-glib package, version 0.1.9, is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) Changes in this release: - Require glib2 >= 2.36.0 - Add support for spiceport chardev - Misc fixes to build system - Fix ref counting of snapshot devices - Add API for deleting snapshots - Fix RPM layout for vala files - Fix race in build of vala code - Add API for getting security models - Add classes for dealing with CPU models - Fix enum generation - Add API for fetching snapshots libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable forever, with libvirt-glib we are not currently guaranteeing that libvirt-glib libraries are permanently API/ABI stable. That said we do not expect to break the API/ABI for the forseeable future and will always strive avoid it. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH] Add new 'kvm' domain feature and ability to hide KVM signature
by Alex Williamson 20 Aug '14

20 Aug '14

QEMU 2.1 added support for the kvm=off option to the -cpu command, allowing the KVM hypervisor signature to be hidden from the guest. This enables disabling of some paravirualization features in the guest as well as allowing certain drivers which test for the hypervisor to load. Domain XML syntax is as follows: <domain type='kvm> ... <features> ... <kvm> <hidden state='on'/> </kvm> </features> ... Signed-off-by: Alex Williamson <alex.williamson(a)redhat.com> --- If it's not obvious, this patch is derived from copying and modifying the similar hyperv feature support.

Re: [libvirt] [PATCH] numatune: setting --mode does not work well
by Erik Skultety 20 Aug '14

20 Aug '14

I see your point, yes, you are right, a leak might occur and I'll fix it in the cleanup phase. Just to be correct, it is not related to the error-check you pointed out. It is because up until now, numatune was only a local duplicate pointer to an allocated memory which was referenced by *numatunePtr (passed as argument). And this was the core of the bug, working directly with a pointer passed to the function. If any problem occures, that pointer should stay untouched, that's why I slightly changed the allocation, thus unfortunately creating a possibility for the leak. So I'm putting another 'if(create)' clause inside the cleanup phase in PATCHv2.

[libvirt] [PATCH] examples: test: Kill unsupported maxMemory element
by Peter Krempa 20 Aug '14

20 Aug '14

The "maxMemory" element was never supported by libvirt. Remove it from the test XMLs.

[libvirt] [PATCH] numatune: setting --mode does not work well
by Erik Skultety 20 Aug '14

20 Aug '14

When trying to set numatune mode directly using virsh numatune command, correct error is raised, however numatune structure was not deallocated, thus resulting in creating an empty numatune element in the guest XML, if none was present before. Running the same command aftewards results in a successful change with broken XML structure. Patch fixes the deallocation problem as well as checking for invalid attribute combination VIR_DOMAIN_NUMATUNE_PLACEMENT_AUTO + a nonempty nodeset.
